Ticking sound from the engine

Asked by GuruVZNHS Aug 05, 2018 at 08:38 AM about the 2012 GMC Yukon SLT

Question type: Maintenance & Repair

my GMC Yukon was making a ticking sound during idle, then it became faster as the enging rev'd.  two mechanics said it was a lifter and quoted a ton of work to do.  after not driving the car for two days, the ticking has now stopped.  does this mean the lifter is really okay?

You can try this with no promises but add some Lucas Engine Oil Stabilizer to oil had a ticking on my vehicle and that took care of it.

Try checking your wheel bairings....I think I had the same problem on my 2001 GMC Yukon Denali xl...that sound was annoying....
